摘要
为改善轨道对地绝缘,降低杂散电流的泄露程度,提出一种基于硅基绝缘材料的轨道复合绝缘技术。结合试验验证和仿真分析手段,对轨道样品进行老化、疲劳及绝缘方面的试验与仿真,检验该绝缘技术在提升轨道对地绝缘性能方面的适用性。结果表明,硅基绝缘材料在轨道绝缘技术中的应用效果良好,可有效改善轨道对地绝缘,并具有良好的稳定性和可靠性。
To improve rail-ground insulation condition and reduce stray current leakage,a rail composite insulation technology based on silica-based nano insulation material is proposed.With combined test verification and simulation analysis methods,tests and simulations of aging,fatigue and insulation are carried out on rail samples,inspecting the applicability of the insulation technology in improving rail-ground insulation performance.Results show that the application outcome of silica-based insulation material in rail insulation technology is good,which can effectively improve the rail-ground insulation and demonstrate good stability and reliability.
